The effects of cyclic heat treatment and hot deformation on the spheroidization and orientation of the TC17 titanium alloy were investigated using a light microscope (LM) and electron backscattered diffraction (EBSD). The experimental results indicate that in the two-phase temperature range of a simple, cycle heat treatment, the spheroidization of the lamellar microstructure of the TC17 titanium alloy is finite. After cyclic heat treatment and compression deformation, the Widmannstatten structure disappears, the spheroidized α lamellae is more obvious, but the uniformity of its orientation is not greatly improved. In addition, the recrystallization velocity, and the strength and toughness of the two phases in deformation lead to a difference in their orientation, and the recrystallization velocity of the α phase is faster than that of the β phase. In the deformation process, the anisotropy of the α phase is preferentially reduced. On the other hand, during the hot deformation process, the degree of deformation of the α phase is lower than that of the β phase, because the α phase is harder than the β phase. The strain is primarily concentrated on the softer β phase adjacent to α phase, which produces greater uniformity in α phase than in the β phase.

The aim of this study was to analyze the relationship between Pro12Ala substitution in the peroxisome proliferator-activated receptor gamma (PPARy) gene and non-alcoholic fatty liver disease (NAFLD). Ninety-seven patients with NAFLD and 51 healthy subjects were included in the study. The height, weight, abdominal wall fat thickness, blood pressure, serum triglyceride, total cholesterol, high-density lipoprotein (HDL) cholesterol, fasting glucose level, hip and waist circumference, and body fat percentage were measured. The PPARγ Pro12Ala genotypes were analyzed using oligonucleotide microarray. Among the NAFLD patients, 11.34% (11/97) had the GC genotype (Pro/Ala) and 88.66% (86/97) had the C genotype (Pro). Among the healthy control group, 5.88% (3/51) had the GC genotype and 94.12% (48/51) had the C genotype. There was no significant difference in the distribution of PPARγ Pro12Ala polymorphism between the NAFLD patients and control subjects. There was no significant difference between PPARγ Pro12Ala polymorphism distribution or blood pressure, weight, body mass index, hip circumference, waist circumference, waist-hip ratio, percentage of body fat, abdominal wall fat thickness, fasting serum glucose, triglyceride, or total cholesterol when compared between these genotypes. No association between PPARγ Pro12Ala substitution and non-alcoholic fatty liver disease was found in the study.

The paper analyzed echo path of mine-used IP broadcast and talkback system, pointed out that the echo has complex sources, long path delay and large path delay jitter. It proposed a scheme of using software algorithm to eliminate echo in radio host, and using combination of structure design and hardware design to eliminate echo in broadcasting terminal. The practical application shows that the scheme of echo cancellation improves communication quality of mine-used IP broadcast and talkback system, and full-duplex loud-speak and talkback of the system has good effect.
